Types of Filtration Systems Used for Wastewater Applications

January 23, 2021

The process of liquid filtration is crucial for ensuring the safety of water inside systems where that water gets reused. It involves the removal of particles and various media and contaminants from liquids so it can keep recycling through the system.

High-quality filtration is important in these systems for a variety of reasons, including reduced overall waste, lower water usage levels and lower chances of consuming harmful chemicals.

There are a couple types of filtration that are used in wastewater treatment systems. Let’s take a brief look at filtration water treatment processes and their applications in Camden County, MO.

Particle filtration

Particle filtration systems are designed to separate solids from liquids with either mechanical or physical solutions. This is typically used as the first step (or one of the first steps) in treating contaminated wastewater, and will be effective for removing any solids larger than one micron.

There is a wide range of specific filter types that can be used for particle filtration. Here are a few options:

  • Bag filters: Bag filters are ideal for smaller applications and systems. These filters are shaped like elongated bags. Wastewater flows into the bag, which catches the solid particles and only allows clean water to flow through its pores to the other side of the system. Bags come with different pore sizes to allow you to catch various sizes of contaminants. This is a cost-effective filtration option that will accumulate less total waste, but it’s not as versatile as other types of filters.
  • Self-cleaning filters: These filters are distinguishable due to their ability to clean themselves, which makes them unique from other filters. They’re in high demand, and also quite versatile due to their customizability. They’re ideal for systems that cannot be shut down to be cleaned.
  • Cartridge filters: These filters feature a pleated fabric or screen that traps particles and chemicals as part of their filtration process. You can find these filters in a couple different varieties: depth filters and surface filters. The latter retain particles on the surface of the liquid, and the former use a media that retains particles after the liquid flows through.

Membrane filtration

The other primary category of filtration in wastewater treatment systems in Camden County, MO is membrane filtration, which is an ideal option for environments in which particle filtration alone will not offer a high-enough quality of filtration. If you need extreme cleanliness out of your water, membrane filtration will give you the highest water quality.

Reverse osmosis is one type of membrane filtration system. This process helps to remove tiny organic particles that might not be caught in other filtration methods.

Ultrafiltration and microfiltration are also available options in some circumstances, usually as a precursor to reverse osmosis. This type of system is performed in low-pressure environments, in which water gets pushed through the filter’s tiny pores to remove any type of contaminants.
